9) Non-stabilized appch.

This accident is where the pilot flies an unstabilized approach and never discontinues the approach, but instead forces the plane onto the runway. The result is usually a long landing going off the opposite end. Depending on the terrain and circumstances, not all accidents are fatal, but each result in a runway excursion either laterally or past the end. The FAA asks for stabilized approaches in numerous documents for GA but never defines exactly what criteria defines a stabilized approach.
